TypeError: expected a character buffer object

Question

I am running into the following error while writing the value into a file. Can you please help me figure out what is the issue here and how to fix it?

row = 649
with open(r'\\loc\dev\Build_ver\build_ver.txt','r+') as f:
    f.write(row)
print row

Error:

Traceback (most recent call last):
  File "latest_rev.py", line 6, in <module>
    f.write(row)
TypeError: expected a character buffer object

Answer 1

假设您只想将字符串'649'写入文件，将row更改为'649'或发出f.write(str(row)) 。

Answer 2

你可以做 timgeb 所做的或者你可以做的

row = str(649)

Answer 3

I had the same error, in my code:

s.translate(table)

The s obj was string . The issue was s.translate was expecting a unicode string. So, the fix was to use:

unicode(s).translate(table)
